# Selectable Stars

Tk supports "active" properties on canvas items that take effect when the
mouse is over the item, so highlighting stars when you mouse over them is
easy.

It's also easy to bind a function/method to <Enter> events and then e.g.
update a status bar or HUD widget or something.

When you click on a star it should "select" it
- populate GUI for star
  - panel on the side?
  - dedicated tab?
- maintain history list of stars to help track what you've been looking
  at (memory aid)
- Select planets to queue orders.
